Will this be an on road only kart? The live axle will cause tire scrub on pavement, the stub axle is actually preferred for on pavement use as it allows tight turning radius. I would be hesitant to use a standard steel axle for a hard ram kart. A 1.25" or flexproof axle might do better. I know the kart racers use hollow chromo axle that have some flex without bending. Probly not cost effective in this use. Think about adding a center support bearing to keep the flex to a minimum.
